Fix Version/s: None
The changes from d789bca that were made as part of
SERVER-18498 made mixed version replication tests use protocol version 0. At the time, this was necessary because the "last-stable" version referred to 3.0 and protocol version 1 wasn't supported; however, it doesn't look like we updated any of the modified multiversion tests to use protocol version 1 since we branched.
